摘要:

特征选择在过去的几十年里在机器学习中引起了广泛的关注,因为它可以在保持特征的原始物理意义的同时降低数据维度,这使得比特征提取具有更好的可解释性。然而,大多数现有的特征选择方法,特别是基于深度学习的方法,通常只关注具有大的重要性分数的特征,而忽略了训练过程中具有较小重要性分数的特征以及重要候选特征的顺序。这可能是有风险的,因为在训练过程中可能会不幸地忽略一些重要和相关的特征,从而导致次优解决方案或误导性选择。在我们的工作中,我们处理的特征选择,利用具有较低的重要性分数的功能,并提出了一个特征选择框架的基础上,一个新的互补特征掩模。我们的方法是通用的,可以很容易地集成到现有的基于深度学习的特征选择方法中,以提高它们的性能。在基准数据集上进行的实验表明,该方法可以选择比现有技术更具代表性和信息量的特征。

英文摘要:

Feature selection has drawn much attention over the last decades in machine learning because it can reduce data dimensionality while maintaining the original physical meaning of features, which enables better interpretability than feature extraction. However, most existing feature selection approaches, especially deep-learning-based, often focus on the features with great importance scores only but neglect those with less importance scores during training as well as the order of important candidate features. This can be risky since some important and relevant features might be unfortunately ignored during training, leading to suboptimal solutions or misleading selections. In our work, we deal with feature selection by exploiting the features with less importance scores and propose a feature selection framework based on a novel complementary feature mask. Our method is generic and can be easily integrated into existing deep-learning-based feature selection approaches to improve their performance as well. Experiments have been conducted on benchmarking datasets and shown that the proposed method can select more representative and informative features than the state of the art.
